Abstract

The removal of SO₂ by NH₃ gas injection at various temperatures and moisture contents has been studied experimentally. The product compositions of the NH₃-SO₂-H₂O vapor reactions were also reported. A thermodynamic analysis was carried out to predict the SO₂ removal as well as the product compositions. Both the experimental results and thermodynamic analysis indicated that SO₂ removal and the product compositions are sensitive to the reaction temperature. Moisture content, once in large excess of the stoichiometric requirement, does not have a strong effect on the product compositions but plays an important role in the SO₂ removal.
